Marshall Wace, a London-based hedge fund manager, has shown a significant drop in the profits it shares out between the members of its partnership, due to reduced income from performance and management fees in the aftermath of Lehman Brothers' collapse.

The results for Marshall Wace LLP, which provides investment management services, reported a group profit available for division among members of £45.5m in the 12 months to February 2010, according to the financial statements of Marshall Wace LLP, which have just been published at Companies House.
